One way to do it, in your NSTableViewDelegate's viewForTableColumn -function:

if tableColumn!.identifier == "description" {
    let cell = NSTableHeaderCell()
    cell.title = "New Title"
    cell.backgroundColor = NSColor.redColor()
    cell.drawsBackground = true
    cell.bordered = false
    cell.font = NSFont(name: "Helvetica", size: 16)
    tableColumn!.headerCell = cell
}
